Open-air cinema in summer is already popular and you can hear classical music in “Open Air Concert”. But it is rare to hear a contemporary music concert outdoors. Ernst-Reuter-Platz in Berlin is situated in the middle of the roundabout of 5 big streets. The central island is decorated with benches, flower beds and a huge fountain. Since 2020, there has also been a “bauhaus reuse” pavilion. You can truly hear future music with different environmental sounds. What percentage of my music can be heard in this place? Or the question is: what new sounds are created when my music is mixed with public noise?
